I always wondered why so many people have this meter. Thanks for the review!
It really is popular !
I was watching some of your older videos and came across this review. I have had this meter for over a decade. When I went back to night school at my local Vo-Tech to get certified in electronics They gave me this meter along with some other hand tools as part of the graduation package. It sits on a shelf now, but I used to keep it as my extra meter in my tool bag. It has survived temperature extremes and has been dropped a couple of times and still survives just fine. So you are right it is a tank.
It's a solidly built multimeter for sure. Probably one of the better built CHEAP-Os Glad to hear it served you well Tron👍
Simply superb. Gud review 👏
Keep On Testing !
i used to have a clone without a brand similar to this. 😅
keep up the good work 👍.
Hi. Great video 😅 I have one real Mastech 830 without backlight that I bought on 2008 and it rules 😅 it was tested by an electrician friend and compared with a Fluke type. He said that the error was minimal and it was very good for the value 7.5€ 😅
It's a solid multimeter! Definitely a great CHEAP-O 👍 Yours is over 15 years old so it ls a testament to the excellent build!
Super
Mastech, has certainly gone downhill over the years. Way back when, they were one of my favorites. Shocked by these results. (btw: Terrific review, Darren!)
You and me both! Hopefully Mastech will wake up and bring back some of that forgotten glory.

You might need to change the 9v battery inside the multimeter, mine did similar so switch out the old battery for new and it was so much better
Good review, kind of sad though, with that build quality it should be a better meter. The Mastech that Harbor Freight sells under their Centech brand is the favorite meter of a friend of mine.
I totally agree. If only it performed as well as it was made!
If your multimeter will tolerate the lower voltage of a rechargeable battery install some rechargeable batteries. Rechargeable batteries don’t leek. Nice review. 👍
Good advice! Yes, those Dura-HELL batteries have let me down a few times now. I'm officially done with them. No sense in paying more while getting less.😉
No hfe transistor test?
Thanks darren its good that i purchased ut33d+ not mastech
You are a saviour!!😍😍 In india mastech costs around₹500 or 10 Canadian dollars and uni t about ₹650 or 12$ to 13$.
Thank God I didn't bought this crap
Glad it helped..definitely UNI-T is the better buy!
Why are current sensing resistors inferior to current shunts?
Not inferior but not as robust when there's alot of current flowing.. I'll take a nice big shunt anyday.
This or the Uni-t 33D.

Absolute beginner, if you have any recommendations too let me know.
Thanks
RICHMETERS RM406B ruclips.net/video/9nIhdrv2ylA/видео.html is a personal favorite of mine in the CHEAP-O Realm..its faster ranging than my 400$ SANWA and can do everything you can imagine. Yes, the Mastech is a solid little dmm that has a huge loyal following and would be a great second choice..though in a different league than the RICHMETERS..😄👍
@@KeepOnTesting could you tell me the model number of sanwa multimeter which you recommend and use.
@@karanpanchal3608 SANWA PC700 is my personal favorite , its a great DMM!
Hi Darren. Mastech seem to do better with slightly higher end meters.
So true..
Too bad because I really wanted to like this little green tank!
I got a clone delivered today from Flipkart, on the body it was showing the model number MAS830L, BUT when I opened it I found XL830L on its chip and exactly similar to the one you have shown in this video that too without that cheap fuse or any other. I have made a return and refund request.
Good job,yes often times they will try to pass the Mastech OEM with a clone
Sir could you please tell me what is the value of R12, R13,R14,R15 my R14 is burnt and my readings are getting messy. I want to replace it. Please help me
Give me 24 hrs and I'll report back with their values 😀👍
R12= 90kΩ R13=9kΩ R14=900kΩ R15=100Ω
@@KeepOnTesting thankyou sir you helped me a lot. Love You. You saved my precious money, time and energy. ummmuaah
@@tanpurev Anytime 😊
Your clone is CE certified for Europe so maybe the Chinese had to work harder in getting it right?
Have you reviewed Mextech MAS830L?
No I have not, sounds like a Mastech clone. Can you send me a link?
@@KeepOnTesting Surprisingly, it is out of stock on many e-commerce sites now. But you can check out its specifications and reviews. My biggest concern is that which one is the original manufacturer of this model MAS830L? I've read some reviews that mention Mextech is good in quality and Mastech is a cheap Chinese copy of Mextech. I'm confused. The Mextech one is of high quality, I had ordered it previously from amazon.in for ₹550, but had to return it because I didn't liked it, it had a major design flaw and it is same for the Mastech which is the battery needs to be installed by removing the whole back plate which is very difficult as it has those two locks inside on the top which get tricky most of the time. After installing the battery it would not close properly even after proper locking and the two screws in the middle on each side would keep on rotating no matter how much you keep them tightening, and sometimes they get tightened up but still there was loose fitting of the front and back, which was the similar issue I had read many user reviews from customers on amazon.in complaining. And for a person like me it would be very inconvenient to remove, reinstall the 9v battery everytime I need to use it. First time they had sent me the probes were missing, design flaw was persistent on second time delivered product as well which was a replacement product, but this led me to return it. If you get hands on with this Mextech do make a review comparing it with Mastech. I am thinking of directly asking the company Mextech as well as Mastech separately via email which one is authentic.
You can check out this on amazon.in with this link but it is currently out of stock. It was in stock when I had checked day before yesterday for ₹810. www.amazon.in/dp/B01BHML9M2/ref=cm_sw_r_cp_apa_i_udNaFbFK1Y5RV
It is currently in stock on industrybuying.com www.industrybuying.com/digital-multimeters-mextech-ME.EL.DI.430346/?Google&PLA&PLAM_New_Testing_and_Measuring_Instruments&gclid=EAIaIQobChMIjffYtLW36gIVmXwrCh1XMgevEAQYASABEgLjwPD_BwE
You can also try Google search if you want more details about this product on their official website it is made in India, Mumbai. But please do a comparison of this with Mastech if you get it in your region in stock. Where do you live?
@@bhushan9066 Thanks for the detailed 👌 info! I'm located in 🇨🇦 Canada. I would love to get my hands on this Mextech and review it. I'll let you know how I make out. Please do keep us updated with your search!
Hiee, sorry to disturb but i have a request, can you please tell me the value of the resistors in original mastech 830L of R13, R14, R15 my R14 resistor blown completely & I'm pretty sure R13 & R15 are affected too, please if possible 🙏
No problem, let me find the multimeter and I'll check..give me 24 hrs.. 😉👍
@@KeepOnTesting thank you so much, but i found out the values of those resistors in comment section, but now i just want to know the value of R17 resistor.
Can you say me the value of r18 it is blown in mine
Value R18= 1Ω
@@KeepOnTesting thank you for your help
Somewhat a disappointment this Mastech meter. A shame, because Mastech does put out some decent meters, etc. Thanks for the review of it. I usually like the manual ranging meters, many of that type seem to have a faster response time.
Definitely! If the performance matched the build quality this would be one heck of a multimeter!
How could the solder blob increase the resistance of the shunt? Current will flow through the shunt anyways, external additions don't really change anything. The only way to change the resistance would be to change the cross sectional area of the shunt, and that is done by crimping/pinching it to make a part of it thinner and thus calibrate it.
Is it true rms meter I have but didn't knows
NO, this multimeter isn't TRMS.
@@KeepOnTesting thanx 😊👍
What is the value of R14 and R15??
I'll have that info for you in 48hrs!
@@KeepOnTesting ok
I will wait 😊😊😊
@@sachinrajput1768 Give me 10 min my friend, checking now..
@@sachinrajput1768 R14=900k R15=100Ω
Well, 9v battery, no ac amps, slow continuity, backlight... Not bad for purchase 20 years ago. But today, no, thanks )
Indeed...this Mastech needs a major update!
So many clones of this style meters are junk, but I had higher expectations for this mastech rendition, the build quality was very credible for the price range, but good build quality is sadly wasted here due to lackluster performance - this mastech didnt really live up to its pedigree. Usually a mastech is a good affordable choice in most cases, but this wasnt one. There are many much better choices in this price range from the likes of UNI-T and a host of others..
Roger that...great build aside its performance kept me scratching my head..its really a shame the OEM was spot on accurate and the Mastech just couldn't match its accuracy. That continuity was terrible on both units, definitely an engineering design that needs improvement.
Did like those solid jacks though
@@yambo59 Yes sir..sexy as hell they were..that pcb was gorgeous actually even the lcd retention for the display was high end for such a cheap multimeter.
Frankly ive never looked even twice at one of these since the only one I bought was so bad, I also have an old no brand XL830L and the range switch arms broke one after the other, they were made of just plain case material and after a few months or so they started falling apart. I still have it, sadly the electrics still work fine but the range switch now feels like a volume knob-lol I dont know what keeps me from throwing it away. I do wish other meters had the jacks this one did though, what a waste of a good build effort.
